Letters Patent No 107 ,47 8, dated September 20, 1870.

IMPROVEMENT IIN' LUBRICATORS The Schedule referred to :ln these-Letters Patent and making part of the name.

To all whom it may concern:

Be it known that I, JOHN GATES, of Portland, in the county of Multnomah and State of Oregon, have invented a new and improved Oiler; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawingforl'nin g part of this specification.

My invention relates to Oilers, and consistsl in an improved construction of parts, which will be specified inthe summary or claim at theend of the specification.

Figure 1 is -a sectional elevation of my improved oiler, taken through the line y y, tig. 2.

Figure 2 isa horizontal section ofthe same, taken on the line :t :z: ot' tig. 1.

Similar letters of reference indicate corresponding parts.

A represents a hollow glass cylinder; and-- B, a metallic vessel attached thereto, and provided with brackets C, or o ther means for attaching to any support.

'Ihe glass part is closed at the top, and provided with a iilling-cup, D, with a tube, D', foi` passing through the cover, and preferablyinto the vessel B.

B' is a stop-cock in the pipe D'.

E represents'passages from A to B.

F represents a pipe leading fromth'e steam-boiler, or any other watersupply higher than the oil or under pressure, into the top of vessel A.' It is provided with a cock, f

H is another water-pipe connection attached to the vessel B, near the bottom, and provided witha cock.` K is the feed-pipe, leading from the top of the cyl-- inder A to the place to be lubricated. It is provided with a cock, L.

vM is a discharge-pipe.

The operation is as follows:

The vessels are filled with oil, or partly with oil and partly with water. The water, being the heavier, will go to the bottom, and the oil will float on it. If the feed is to be slow the oook G is opened, so as to let the water drop into the oil as fast as it is required to.

have the oil flow out. The latter will be expelled by the water, which will sink to the bottom of the oil.

If the part to be lubricated is above the vessel, the column of water should be of sufficient height to raise the oil.

`If it is required to feed in jets, then I prefer to admit a corresponding jet of water through the. pipe H at the bottom, for, if a considerable quantity of water be admitted at the top, it would be liable to mix with the oil owiug out of the feed-pipe..

This method 'of feeding admits of observing the quantity and regularity of the feed, as the water,- dropping into the oil and falling to the bottom, may be distinctly seen through the glass.A

IIhen the oil is exhausted, the water in the vessel may be drawn oi through thecock M', and a new supply 'of oil added, as at first.

- I have shown the vessel B, in this example", merely as a convenient-means of attaching the apparatus to any suitable support, butneed not necessarily use it,

as any other attachment for the glass vessel mayb used.

'Ihe vessel may be made wholly of glass, if preferred,

and a drip-cup may be attached to the bottom for securing the dripping oil. y A

For the slow feed the vessel may either be open, to expose the oil to the atmosphere, or closed. For feeding it in jets it should be closed.

Having thus described my invention,

I claim as new and vdesire tosecure byLetters Patent- The hollow glass cylinder A, vessel B, tube D', and pipes F K, all constructed and relatively arranged as shown in tig. 1 of the drawing, and for the purpose specified.

4The above specification of my invention signed by me this 1st day of March, 1870.

JOHN GATES.
